Abstract

Procédé de brossage d’une arête (15) d’au moins une alvéole (12) usinée à la périphérie d’un disque (10) de turbine, à l’aide d’une brosse (16) montée sur une broche commandée par un robot, chaque alvéole (12) s’étendant en creux entre deux extrémités circonférentielles (13a, 13b) à la périphérie (11) du disque (10), le procédé comportant les étapes suivantes : mettre en rotation la brosse (16) autour de son axe de rotation (z),brosser, à l’aide de la brosse (16), un fond (20) de ladite au moins une alvéole (12) en positionnant la brosse (16) dans une première position angulaire prédéterminée dans laquelle, par projection dans un plan (XZ) du disque (10), son axe de rotation (z) forme un angle positif non nul avec une direction radiale (Z) du disque (10) au niveau de l’alvéole (12),brosser, à l’aide de la brosse (16), le fond (20) de ladite au moins une alvéole (12) en positionnant la brosse (16) dans une deuxième position angulaire prédéterminée dans laquelle, par projection dans le plan (XZ) du disque (10), son axe de rotation (z) forme un angle négatif non nul avec la direction radiale (Z) du disque (10) au niveau de l’alvéole (12),répéter les étapes b et c au moins dix fois en alternant la première position angulaire prédéterminée avec la deuxième position angulaire prédéterminée. Figure de l’abrégé : Figure 3Method for brushing an edge (15) of at least one alveolus (12) machined on the periphery of a turbine disk (10), using a brush (16) mounted on a spindle controlled by a robot, each alveolus (12) extending in a hollow between two circumferential ends (13a, 13b) at the periphery (11) of the disk (10), the method comprising the following steps: rotating the brush (16) about its axis of rotation (z), brushing, using the brush (16), a bottom (20) of said at least one alveolus (12) by positioning the brush (16) in a first predetermined angular position in which, by projection in a plane (XZ) of the disk (10), its axis of rotation (z) forms a non-zero positive angle with a radial direction (Z) of the disk (10) at the alveolus (12),brushing, using the brush (16), the bottom (20) of said at least one cell (12) by positioning the brush (16) in a second predetermined angular position in which, by projection in the plane (XZ) of the disk (10), its axis of rotation (z) forms a non-zero negative angle with the radial direction (Z) of the disk (10) at the cell (12),repeating steps b and c at least ten times by alternating the first predetermined angular position with the second predetermined angular position.
